I have a basic computer on my 2003 2500 6.0 5spd. Besides the code in the topic, all it show is hours, trip and odo in an option of English, Francias, and espanol?

 

Sometimes i can trigger this code while messing with the reset button, other times it just randomly shows this code when I am near or in my truck, even without a key on me or in the ignition.
